Ich lerne DirectX (DirectX 9) von www.directxtutorial.com und verwende Visual Studio 2012 unter Windows 8. d3dx9 (d3dx) wird durch andere Header wie DirectXMath ersetzt, daher habe ich alles Notwendige ersetzt, aber es gibt ein Problem - konvertiere XMMATRIX nach D3DMATRIX.

Der Problemcode (Das geschriebene Problem - /Problem!/):

void render_frame(void) {
// clear the window to a deep blue
d3ddev->Clear(0, NULL, D3DCLEAR_TARGET, D3DCOLOR_XRGB(0, 0, 0), 1.0f, 0);

d3ddev->BeginScene();    // begins the 3D scene

// select which vertex format we are using
d3ddev->SetFVF(CUSTOMFVF);

// SET UP THE PIPELINE

DirectX::XMMATRIX matRotateY;    // a matrix to store the rotation information

static float index = 0.0f; index+=0.05f;    // an ever-increasing float value

// build a matrix to rotate the model based on the increasing float value
matRotateY = DirectX::XMMatrixRotationY(index);

D3DMATRIX D3DMatRotateY = matRotateY.r;

// tell Direct3D about our matrix
d3ddev->SetTransform(D3DTS_WORLD, &matRotateY); /*problem!*/

DirectX::XMMATRIX matView;    // the view transform matrix

DirectX::XMVECTOR CameraPosition = {0.0f,0.0f,10.0f};
DirectX::XMVECTOR LookAtPosition = {0.0f,0.0f,0.0f};
DirectX::XMVECTOR TheUpDirection = {0.0f,1.0f,0.0f};

matView = DirectX::XMMatrixLookAtLH(CameraPosition,    // the camera position
    LookAtPosition,    // the look-at position
    TheUpDirection);    // the up direction

d3ddev->SetTransform(D3DTS_VIEW, &matView);  /*problem!*/   // set the view transform to matView

DirectX::XMMATRIX matProjection;     // the projection transform matrix

DirectX::XMMatrixPerspectiveFovLH(&matProjection,
    DirectX::XMConvertToRadians(45),    // the horizontal field of view
                           1.0f,    // the near view-plane
                           100.0f);    // the far view-plane

d3ddev->SetTransform(D3DTS_PROJECTION, &matProjection);  /*problem!*/   // set the projection

// select the vertex buffer to display
d3ddev->SetStreamSource(0, v_buffer, 0, sizeof(CUSTOMVERTEX));

// copy the vertex buffer to the back buffer
d3ddev->DrawPrimitive(D3DPT_TRIANGLELIST, 0, 1);

d3ddev->EndScene();    // ends the 3D scene

d3ddev->Present(NULL, NULL, NULL, NULL);   /* displays the created frame on the screen */ }
